Answer two questions about the followibg table. The cost to park in the downtown parking lot depends on the number of hours you oark your car for.

Hours Parked: 1, 5, 12
Cost (in dollars): 4, 10, 15

Question 2:
Is the cost of parkibg proportional to the number of hours parked?

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

The answer would be 4x+3
